So if I am at a friend's house and only have access to a 120V outlet, can the car be preheated before leaving on a cold morning from the 120V outlet? Is that enough heat to do anything useful, or will preheating deplete the battery?
I'm looking at ABRP and it is telling me even starting at 80% charge I need to charge before reaching my destination 184 miles away. Arrival minimum is set to 10% (100 kWh battery with 6% loss). I calculate this as 2.8 miles per kWh, or in the car's terms, 360 kW/mi. That should not be hard even with a bit of heat. It wants me to stop about halfway to charge for 5 minutes, +11%. I'm thinking a warmup of the battery might get be the bit I need to arrive with enough to spare. But I suppose it is no better to warm the battery than it is to charge it. I only get the 80% if it charges all night.
The car is scheduled to arrive at the intermediate charger with 42% remaining. So I expect the car will be conditioning the battery. It's only 85 miles, but an hour 45 minutes driving (the first 30 miles are back roads) and I don't think the battery will be warm on it's own. It will get down to 24°F tonight. Will the 1 kW charging do much for the battery temperature?
